UN Class 1

Justification for classification or non-classification

According to the CLP Regulation (EC) No 1272/2008, 2.1.2 section, classification criteria, substances, mixtures and articles are classified for explosive hazard on the basis of the experiment results, obtained in tests conducted according to the test methods described in Part I of the UN Recommendations on the Transport of Dangerous Goods – Manual of Tests and Criteria.

The classification in the explosives hazard class and further allocation to a division follows a step-by-step procedure. In in this case case, the DSC measurements showed a maximum energy release between 500 and 800 J/g. Therefore, the Koenen-Test (UN-tests 1(b), 2(b) and E.1) and the Time-Pressure-Test (UN-tests 1(c), 2(c) and C.1) had to be performed. From the UN-tests 1(b) (effect of heating under confinement) and 1(c) (effect of ignition under confinement) the question "Is it an explosive substance?" can be answered in the negative. Therefore, the test item can be excluded from classification in class 1 (explosives) according to series 1 of the "UN Recommendations on Transport of Dangerous Goods – Manual of Test and Criteria" and the criteria to classify the substance as explosive are not met, according to the CLP Regulation (EC) No 1272/2008.
